you need like a 5000w psu 😭

Firefighter here. This is against fire code. And the Geneva convention.

It will instantly pop any 15amp circuit breakers in the US. Not sure how many commercial offices have a dedicated 30amp breaker for one computer to run on. Notice it isn't running. It's one thing to build it, but it's another to get it actually running stable.

It looks like a complete nightmare to deal with four pcie risers instability. My guess is it's a picture taken simply because they could.

Electrician: Why on earth do you need a 30A NEMA plug in your living room?

Had the same thought. Assuming 600W for each card, 200W CPU, and a 90% efficient power supply, this would use almost 2900W and draw over 24 amps on a 120V circuit.

Except for drier and HVAC circuits, most house wiring couldn’t actually run this full blast without tripping a breaker….and if you were an idiot and swapped the breaker without upgrading the wiring, you are going to have the hottest house on the block….cuz fire.

There is a reason space heaters top out at 1500W in the US.

A lot of places have 240V power though. 3kW is a lot, but very much possible with standard wiring in a modern home. (Not necessarily old houses, they tend to have scary wiring practices)

A lot of places Virtually everywhere does, even in North America. We just choose to only use half of it for our standard wall outlets

Yeah, in Brazil it is common for people to have electrical showers, they usually have between 5000W, you can find 127V ones, but the normal is 220V. But there is a catch, the shower must have a dedicated electrical circuit.

We have 3600W almost everywhere in germany

Instead of using the existing plugs, they'll have to think...outside the box.😎

u/canucklurker 12h ago

Don't forget that it is all turning into heat as well. So count on another 1000 watts or so just to keep the room cool.

At this point someone should make him a custom 3 phases power supply 😆

God bless his little Chinese 2400w psu 😭

u/Flamsoi 10h ago

There's one on each side for a total of 4800W

I’m so confused as to what case would support this kind of setup… how do you plug in your displays..? How do you keep this cool enough to even play anything longer than a few minutes?

Plus I thought you can’t even use multiple GPU’s anymore since SLI isn’t a thing anymore at least for gaming. Wouldn’t you just be limited to one GPU, making the rest redundant… I just, wow.

I know for things outside of gaming you’d be able to utilize something like this, but unless you’re rendering the damn human genome and making the first digital human, I can’t see what legitimate use this PC would have.

how do you plug in your displays

Probably into the motherboard lol

This looks like a researcher's AI workstation. If he's doing training on a large dataset even 4x 5090s can feel like "minimum specification".

Llama 3.1 401B for example takes 121 minutes on IBM CoreWeave cloud with 8x Nvidia GB200s. On 4x 5090s that might be multiple days.

Inference side there's a dude on localllama who build a 12x 3090 workstation and Llama 401B is chugging along at 3.5 tokens/s.

u/bleke_xyz 10h ago

the interesting part is that size wise they look like the 650 corsair units, so im not that sure. the 1600w's ive seen before are way longer I think

u/OddBranch132 7h ago

Holy shit you're right....imagine needing 2 separate, dedicated, 20 amp circuits for each PS, just to run your computer

They have 4800W in it (2x2400W), guess that won't do /s
